Abstract
Telexistence, tele-existence, or telepresence, is an advanced form of tele-operation, which enables a human operator to remotely perform tasks with dexterity, providing the user with the feeling that he or she is present in the remote location. As a matter of fact, some fictitious robot control systems in novels, comics, animations, and movies precede real robot control systems. In this paper, we will review the history of telexistence robots, both in terms of current technology and science fiction, with paying special attention to display and operation aids.
